Abstract Kiwifruit vine decline syndrome (KVDS) is an emerging challenge related to various factors, including water stagnation, soil compaction, root hypoxia, imbalanced redox potential, nutrient imbalance and fungal pathogens, yet its definitive causes remain unconfirmed. This study compared soils roots of healthy plants (CTRL group) affected by KVDS (KVDS at a kiwifruit orchard ( Actinidia chinensis cv. ‘ Zesy002 ’) in Sermoneta (Lazio region), Italy. Our findings indicate that parameter oxidation, macroporosity were significantly lower the soils. The table was also found be higher block orchard, demonstrating content. suggests less aeration more content KVDS‐affected control. Root analyses showed led browning decomposition rhizodermis, decay central stele, detachment cortex, reduced cell size presence starch granules parenchyma, with significant variations morphometric parameters. To mitigate KVDS, sustainable agronomic practices, precision irrigation, green manure, compost addition drainage pruning, carried out on some KVDS‐symptomatic vines (SUST group). Molecular revealed 10 species from treated plants, Paraphaeosphaeria michotii , Fusarium oxysporum Ilyonectria vredenhoekensis being frequently isolated symptomatic but SUST plants. Also, Beauveria bassiana Bacillus amyloliquefaciens effect against I. P . may suitable candidates as biocontrol agents. adoption practices resulted (46% increase) end trial, use management orchards can through restoration natural growth conditions.
